Limestone. Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - CaCO 3 ). There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral ...Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces. The fossils in these rocks may be of macroscopic or microscopic size.3 Types of Sedimentary Rocks. Clastic, Inorganic (chemical), and Organic (Biochemical) Clastic Rocks. - Sediment size of gravel, sand, silt and clay. - Visible grains and clay size particles.
